Chongqing Electronic Circuit Industrial Park is jointly built by Sichuan Lvran Technology Group Co., Ltd., Chongqing Yuhan Electronic Technology Co., Ltd., and Rongchang High tech Zone. The industrial park focuses on professional production of printed circuit boards, with collaborative development of production, education, and research. It integrates copper clad boards, printed circuit boards, SMT chips, electronic components, circuit boards, and electronic equipment. Chongqing Electronic Circuit Industrial Park is a large-scale specialized electronic circuit park with supporting services throughout the entire industrial chain. The industrial park covers an area of 1038acres, with a total investment of 10 billion yuan. The completed investment is 12 billion yuan, and the completed area is 920000 square meters. Daily processing capacity of 20000 meters ³ The wastewater treatment center is planned, constructed, and put into operation according to the four surface standards. The industrial park, in accordance with the requirements of unified planning, cluster development, and green environmental protection, innovatively focuses on attracting investment and providing thoughtful services to promote construction, injecting new vitality into the economic construction of Rongchang.

At present, the park has successfully introduced 56 upstream and downstream supporting enterprises, completed and put into operation 37 of them, including 29 contracted production enterprises. There are 8 designated enterprises in the park, 4 specialized, refined, and new enterprises, 3 digital workshop enterprises, and 1 high-tech enterprise; In 2022, the industrial output value of the park will reach 4 billion yuan, and in 2023, the output value of the park will exceed 6 billion yuan. After all enterprises in the park settle down and reach production capacity, they can produce 40 million square meters of circuit boards annually, with an annual output value of over 20 billion yuan. Every year, it achieves a tax revenue of over 700 million yuan and provides 15000 job opportunities. The park has been successfully established as the "First Batch of Chengdu Chongqing Double City Economic Circle Cooperation Demonstration Parks", "Chongqing Characteristic Industry Base", "Chongqing Science and Technology Enterprise Incubator", and "Key Industry Park for New Energy Vehicle Parts". A complete industrial ecosystem has been formed, including copper clad board, hard board, soft board, and soft hard composite board products, as well as supporting services for key processes such as copper sinking, drilling, internal pressing, and surface treatment, as well as ink auxiliary material distribution. High end PCB production enterprises such as Chongqing Gaozhi Electronics, Wanhexing Electronics, Hong'an Electronics, and Liansen Electronics have successively put into production. Bisjie and Shenzhen Jinxin are about to increase capital and expand production. It is expected that by 2026, more than 7 enterprises will have an annual output value exceeding 1 billion yuan. We have won a reputation in the industry for good environmental protection, excellent service, complete supporting facilities, low cost, and good efficiency, forming a good situation of attracting investment through business and selecting the best ones.
